I'm pretty sure someone posted about this issue two or three weeks ago, but I searched and couldn't find it.

Does it take more yarn using small needles or large needles?

For example, I cast on 40 stitches, and I'm knitting it in the round. I need it to be about 4 feet long, but I need it to be really strong, especially after I felt it, and I accidently started knitting it on size fours. I know that if I use larger needles it will go faster, but which will take more yarn?

I don't think we ever came to a conclusion of any sort. At some point I plan on testing out my theories, but even without testing, I'm 99.9% sure that I'm right. The logic behind it all just seems to make sense to me.

I'll test it out sometime in the next few weeks when I have the chance. Must finish olympic knitting first!

Thanks everyone for the help! I'm going to go with the small needles for now, and see how long one skein ends up being. If it's not even close to being long enough, I'll frog and reknit on bigger needles!
